Description

Technical Field

[0001] This utility model belongs to the field of roller can ear technology, specifically relating to a roller can ear with high safety. Background Technology

[0002] Roller lugs are devices installed on hoisting containers (such as cages or skips) in vertical shafts to work in conjunction with the hoisting guideway to ensure the container runs smoothly along a predetermined path. During use, roller lugs help maintain the hoisting container in the correct position within the shaft, preventing lateral deviation. They also absorb impacts and vibrations caused by shaft deformation, uneven guideway, or operational inertia.

[0003] Roller can handles typically consist of rollers, a swing arm, a damper, and a base. The rollers are in direct contact with the can channel, using rolling friction instead of sliding friction to reduce wear. They are usually made of high-strength, wear-resistant materials with special surface treatments to extend their service life. The swing arm connects the rollers and the base, allowing the rollers to swing within a certain range to accommodate slight deviations in the can channel. It is made of high-strength steel to ensure structural stability. The damper is mounted on the rollers or swing arm to absorb impact energy. Types include spring-loaded, hydraulic, or hydraulic-pneumatic combinations, selected according to the application scenario. The base is fixed to the lifting container, providing installation support. Its design must ensure a secure and reliable connection with the container.

[0004] As a key guiding and buffering device in vertical shaft hoisting systems, the roller ear of the cage or skip is prone to accumulating various debris on its surface during actual use. These debris come from a wide range of sources, including coal slag and ore fragments falling from the shaft, as well as dust and condensate from the shaft walls. Once this debris adheres to the roller surface, it can cause a series of problems during the operation of the hoisting container.

[0005] Because debris alters the original contact state and friction coefficient between the rollers and the guide rail, the rollers cannot roll smoothly on the guide rail. This causes the rollers to jam and bounce during rotation, resulting in irregular vibrations of the lifting container during operation. This vibration not only affects the stability of the lifting container and increases wear between the container and the guide rail, but more importantly, it poses a serious safety risk to the entire lifting system. Utility Model Content

[0006] The purpose of this invention is to provide a high-safety roller can ear, aiming to solve the problem that in the prior art, the roller surface of the roller can ear is prone to the adhesion of various debris. Because the debris changes the original contact state and friction coefficient between the roller and the can channel, the roller cannot roll smoothly on the can channel. This will cause the roller to jam and jump when rotating, which in turn will cause irregular vibration of the lifting container during operation. This vibration will not only affect the stability of the lifting container and increase the wear between the container and the can channel, but more importantly, it will bring serious safety risks to the entire lifting system.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-safety roller can ear, comprising a base plate, a swing arm, rubber rollers, and a buffer cylinder. The swing arm is rotatably mounted on the surface of the base plate, and the rubber rollers are connected to the inner wall of the swing arm. A buffer cylinder is installed between the swing arm and the base plate. A connecting plate is connected to the side surface of the swing arm, and a rotating shaft passes through the interior of the connecting plate. A limit block is connected to the end of the rotating shaft, and a connecting block is connected to the middle of the rotating shaft. A return spring is connected between the connecting block and the connecting plate, and a scraper is connected to the surface of the connecting block.

[0008] As a preferred embodiment of the present invention, which features a high-safety roller can ear, the connecting plate and the limiting block are symmetrically arranged in two sets at both ends of the rotating shaft, and the rotating shaft and the connecting plate form a rotating structure.

[0009] As a preferred embodiment of the present invention, which features a roller can ear with high safety, the return spring is symmetrically arranged on both sides of the connecting block, and the connecting block and the return spring form an elastic return structure.

[0010] As a preferred embodiment of the present invention, which features a high-safety roller can ear, the side surface of the rubber roller is provided with a pressure plate, the side surface of the pressure plate is connected with a positioning post, and the side surface of the rubber roller near the positioning post is provided with a positioning hole.

[0011] As a preferred embodiment of the present invention, which features a high-safety roller can ear, the surface of the pressure plate is provided with a threaded hole, a crossbar passes through the inside of the threaded hole, the crossbar passes through the inside of the swing arm, the surface of the crossbar is connected with a protruding thread, and the end of the crossbar is provided with a hexagonal groove.

[0012] As a preferred embodiment of the present invention, which features a high-safety roller can ear, the pressure plate is symmetrically arranged on both sides of the rubber roller, the positioning posts are arranged in a ring array on the surface of the pressure plate, the positions of the positioning posts correspond to the positioning holes, and the positioning posts and positioning holes form an insertion structure.

[0013] As a preferred embodiment of the high safety of the roller can ear of this utility model, the crossbar, the convex thread and the hexagonal groove are symmetrically arranged on both sides of the rubber roller, and the convex thread and the threaded hole are connected by a thread.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the return spring uses its own elasticity to press the scraper connected to the connecting block onto the surface of the rubber roller. This allows the scraper to remove any adhering substances from the surface of the rubber roller, thus ensuring the stability of the roller can handle when lifting the container and improving the safety of using the roller can handle.

[0016] In this invention, when a hexagonal wrench is inserted into the hexagonal slot and rotated, it can drive the crossbar to rotate. When the crossbar rotates, it can drive the convex thread to rotate inside the threaded hole, which can drive the pressure plate to move laterally. When the two pressure plates drive the positioning pin to move to the outside of the positioning hole, the rubber roller can be removed and replaced with a new rubber roller, which can facilitate the continued use of other parts of the roller can ear, thereby reducing the company's costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution: a high-safety roller can ear, including a base plate 1, a swing arm 2, a rubber roller 3 and a buffer cylinder 4. The swing arm 2 is rotatably mounted on the surface of the base plate 1. The rubber roller 3 is connected to the inner wall of the swing arm 2. The buffer cylinder 4 is installed between the swing arm 2 and the base plate 1. A connecting plate 5 is connected to the side surface of the swing arm 2. A rotating shaft 6 passes through the inside of the connecting plate 5. A limit block 7 is connected to the end of the rotating shaft 6. A connecting block 8 is connected to the middle of the rotating shaft 6. A return spring 9 is connected between the connecting block 8 and the connecting plate 5. A scraper 10 is connected to the surface of the connecting block 8.

[0026] The rubber roller 3 rolls on the tank channel to keep the container stable. The swing arm 2 automatically adjusts the angle of the rubber roller 3 according to the irregularity of the tank channel. When an impact occurs, the buffer cylinder 4 compresses or releases energy to reduce the impact force on the container and the tank channel. The swing range of the swing arm 2 limits the rubber roller 3 to prevent it from derailing.

[0027] Preferably, two sets of connecting plates 5 and limiting blocks 7 are symmetrically arranged at both ends of the rotating shaft 6, and the rotating shaft 6 and the connecting plates 5 form a rotating structure.

[0028] In practical use, when the scraper 10 is subjected to force, it can drive the rotating shaft 6 to rotate inside the connecting plate 5 through the connecting block 8.

[0029] Preferably, the reset springs 9 are symmetrically arranged on both sides of the connecting block 8, and the connecting block 8 and the reset springs 9 form an elastic reset structure.

[0030] In practical use, when the connecting block 8 is subjected to a force and rotates, it can pull the return spring 9 to deform. After the force disappears, the return spring 9 drives the connecting block 8 to reset through its own elasticity.

[0031] Preferably, a pressure plate 11 is provided on the side surface of the rubber roller 3, a positioning post 12 is connected to the side surface of the pressure plate 11, a positioning hole 13 is provided on the side surface of the rubber roller 3 near the positioning post 12, a threaded hole 14 is provided on the surface of the pressure plate 11, a crossbar 15 passes through the inside of the threaded hole 14, the crossbar 15 passes through the inside of the swing arm 2, a protruding thread 16 is connected to the surface of the crossbar 15, and a hexagonal groove 17 is provided at the end of the crossbar 15.

[0032] Preferably, the pressure plate 11 is symmetrically arranged on both sides of the rubber roller 3, and the positioning posts 12 are arranged in a ring array on the surface of the pressure plate 11. The positions of the positioning posts 12 and the positioning holes 13 correspond to each other, and the positioning posts 12 and the positioning holes 13 form an insertion structure.

[0033] In practical use, after the position of the pressure plate 11 is fixed, the position of the rubber roller 3 is fixed by the insertion of the positioning pin 12 and the positioning hole 13.

[0034] Preferably, the crossbar 15, the convex thread 16 and the hexagonal groove 17 are symmetrically arranged on both sides of the rubber roller 3, and the convex thread 16 and the threaded hole 14 are threadedly connected.

[0035] In practical use, the rotation of the crossbar 15 can drive the convex thread 16 to rotate. When the convex thread 16 rotates inside the threaded hole 14, it can drive the pressure plate 11 to move laterally through the threaded connection. The lateral movement of the pressure plate 11 can drive the positioning pin 12 to move laterally. When the positioning pin 12 moves to the outside of the positioning hole 13, the rubber roller 3 can be removed.

[0036] Working principle: When in use, the roller can ear can drive the rubber roller 3 to rotate through friction with the container. At the same time, the return spring 9 uses its own elasticity to make the scraper 10 connected to the connecting block 8 press against the surface of the rubber roller 3. In this way, the scraper 10 can scrape off the adhering material on the surface of the rubber roller 3, thereby ensuring that the roller can ear can improve the stability of the container.

[0037] When the rubber roller 3 is severely worn and needs to be replaced, first fix the rubber roller 3 so that it cannot rotate. Then, use a hex wrench to insert into the hexagonal groove 17 and rotate it. This will drive the crossbar 15 to rotate. When the crossbar 15 rotates, it will drive the convex thread 16 to rotate. Under the limiting action of the positioning pin 12 and the positioning hole 13, when the convex thread 16 rotates inside the threaded hole 14, it can drive the pressure plate 11 to move laterally. When the two pressure plates 11 drive the positioning pin 12 to move to the outside of the positioning hole 13, the rubber roller 3 can be removed and replaced with a new rubber roller 3.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
